A client with coronary artery disease is hospitalized with unstable angina. To reduce cardiac workload, which intervention should the nurse include in the client's plan of care?

Rationale: A. Provide a bedside commode for toileting: Using a bedside commode minimizes physical exertion associated with walking to the bathroom, thereby reducing cardiac workload and oxygen demand, which is critical for clients with unstable angina. B. Encourage active range of motion exercises: While gentle exercises help maintain muscle tone, they increase cardiac workload and are not appropriate during acute unstable angina. C. Teach to sleep in a side-lying position: Positioning affects comfort and may slightly influence hemodynamics, but it does not significantly reduce cardiac workload compared to minimizing physical activity. D. Assist with ambulation in the hallway: Ambulation increases oxygen demand and cardiac workload, which may precipitate angina in clients with unstable coronary artery disease.
